ETHANOL FUEL (E-85)

E-85 is a mixture of approximately 85% fuel ethanol and
15% unleaded gasoline.

WARNING!

Ethanol vapors are extremely flammable and could
cause serious personal injury. Never have any smok-
ing materials lit in or near the vehicle when remov-
ing the fuel filler tube cap (gas cap) or filling the
tank. Do not use E-85 as a cleaning agent and never
use it near an open flame.

Fuel Requirements

If your vehicle is E-85 compatible, it will operate on
unleaded gasoline with an octane rating of 87, or E-85
fuel, or any mixture of these two fuels.

For best results, a refueling pattern that avoids alternat-
ing between E-85 and unleaded gasoline is recom-
mended.

When you do switch fuel types, it is recommended that:

• you do not add less than 5 gal (19 L) when refueling
• you drive the vehicle immediately after refueling for at

least 5 miles (8 km)

Observing these precautions will avoid possible hard
starting and/or significant deterioration in driveability
during warm up.

NOTE:

• Use seasonally adjusted E-85 fuel (ASTM D5798). With

non-seasonally adjusted E-85 fuel, you may experience
hard starting and rough idle following start up even if
the above recommendations are followed, especially
when the ambient temperature is below 32°F (0°C).
